Fast and Reliable File Transfer Protocol

Why This

Traditional FTP

The traditional FTP protocol is efficient in most scenarios.

However, when faced with an unstable network environment, its efficacy wanes considerably. This is largely due to the TCP-based FTP's exponential back-off mechanism, which curtails the transmission rate upon detecting network congestion

UDP-based FTP

This UDP-based file transfer protocol is an alternative solution.

Leveraging multi-threading, this protocol guarantees dependable file transfers between server and client, delivering excellent performance even in high-congestion and high-loss network conditions.

Quick Start

Server Setup

server.cpp:

• Description: The server waiting for the transmission.

• Compile: g++ -std=c++11 -g -pthread ftp_Server.cpp -o server

• Run: ./<target_file_name> <file_to_transfer> <host_port>

• Makefile shortcut:

  make server

Client Setup

client.cpp:

• Description: The client that establish connection with server and sends the file.

• Compile: g++ -std=c++11 -g -pthread ftp_Client.cpp -o client

• Run: ./<target_file_name> <path_to_store_file> <hostname> <host_port>

• Makefile shortcut:

  make client

File Integrity Check

MD5.py:

• Description: Generate the hash code of transferred file.

• Run: python MD5.py
